Abstract: An encoding apparatus and a decoding apparatus for processing a video signal The invention relates to an encoding apparatus for processing a video signal comprising a plurality of frames dividable into video coding blocks. A first video coding block of a current frame of the video signal is partitioned into a first segment associated with a first segment motion vector relative to a first reference frame of the video signal and a second segment. The first video coding block is associated with a plurality of virtual partitions. Each virtual partition is associated with a respective subset of the plurality of video coding blocks of the current frame. Each video coding block of the respective subset neighbors the first video coding block and is associated with a motion vector.

Abstract: A method for coding implemented by a decoding device or an encoding device includes: obtaining a first prediction mode for a first sub-block, obtaining a second prediction mode for a second sub-block; obtaining a first prediction value for a sample in the current block according to the first prediction mode, obtaining a second prediction value for the sample in the current block according to the second prediction mode; obtaining a value of an indicator, the value of the indicator indicating a blending operation which is performed for the sample in the current block; and obtaining a combined prediction value for the sample in the current block, according to the value of the indictor, the first prediction value, and the second prediction value. The blending operation adaptively performs around a separation line dividing the current block into at least the first sub-block and the second sub-block.

Abstract: An encoder is provided that comprises a partitioner and an entropy coder. The partitioner is configured to receive a current block of the frame and obtain a list of candidate geometric partitioning (GP) lines. Each of the candidate GP lines is generated based on information of one or more candidate neighbor blocks of the current block. The partitioner is further configured to determine a final GP line that partitions the current block into two segments, select a GP line from the list of GP lines to obtain a selected GP line, and generate a GP parameter for the current block. The GP parameter includes an offset information indicating an offset between the final GP line and the selected GP line. The entropy coder is configured to encode the GP parameter.
